Here are the five don't miss attractions from both:
Universal:
1. Shrek 4-D
2. Back to the Future
3. Men in Black
4. E.T. (sorry, I just love E.T. though)
5. Jimmy Neutron (not as good as the old Hannah Barbera ride, but still funny. See how many Mick characters you can spot)
IOA
1. The Hulk (simply incredible. What a rush)
2. Spiderman (Best 3-d ride ever!)
3. Dueling Dragons (Second only to the Hulk for Roller Coasters)
4. Jurassic Park (Awesome way to cool off on hot days)
5. Dudley Do-Right's Rip-Saw Falls (Awesome way to cool off even more on hot days)
